ENGINE HEAD.

Application filed July 28, 1922. Serial No. 578,199.

1 '0 all whom it may conceive:

Be it known that I, (:iuoneic Szrui, a citizen of the Republic ofHungary, residing at San Antonio, in the county of Bexar and State ofTexas, have invented a new and useful Engine Head, of which thefollowing is a specification.

This invention relates to engine constructions and aims to provide novelmeans, whereby the usual engine may be converted into an engine of thevalve-in-the-head type.

Another object of the invention is to provide an engine of thischaracter wherein the usual valve guides may be utilized as push rodguides employed for transmitting motion of a cam shaft to the rockers ofthe engine head.

A still further object of the invention is to provide a novel form ofrocker whereby a plurality of exhaust valves may operate in proximity toeach other and be con trolled by a single push rod.

.Vith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in theprcciseembodiment of the invention herein disclosed, may be made withinthe scope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawing Figure 1 is an elevational view of an engineconstructed in accordance with the present invention, a port-ion thereofbeing broken away to illustrate the manner of positioning the push rods.

, Figure 2 is a plan view of one end of the engine disclosing one of thebrackets for supporting rockers.

Figure 3 is a sectional view taken on line 3-3 of Figure 1.

Figure i is a fragniental elevational view disclosing the upper end ofone of the push rods employed for controlling the rockers operating theexhaust valves.

Figure 5 is a plan view disclosing one end of a bracketand rockersupported thereby.

Referring to the drawing in detail, the reference character 5 designatesan engine block which is formed with valve guideways 6.

The head, forming the essence of this invention, is indicated at 7 andis formed with bores 8 to accommodate the push rods 9, the bores 8 beingdesigned to register with the guideways 6.

The head is supplied with exhaust valves 10 arranged in pairs, it beingcontemplated to provide a pair of exhaust valves for each cylinder ofthe engine block to insure the exhaust gases passing from the cylinder.

The intake valve is of a construction identical with that of the exhaustvalves 10 and is operated by means of the rocker 11. Bracket members 12support the rockers 11 and rockers 13 that operate the exhaust valve andas shown, the rockers 13 include a main rocker 14:, and an inner rocker15, the main or outer rocker 15 being relatively large and formed with acutout portion to accommodate the inner rocker 15, whereby the rockersmay be'operated by a single push rod as shown.

The push rods operating the rockers which in turn control the movementsof the exhaust valve, are forked, so that the portion 16 may contactwith the outer rocker 14 while the inner extension 15 contacts with therocker 15 to operate the exhaust valves simultaneously. The valvemembers are returned to their normal or closed positions by means of thecoiled springs 16. A suitable intake is formed in the head whichsupplies fuel to the engine cylinders the intake manifold being incommunication with the head through the openings 17.

It might be further stated that the gasket indicated at 18, is formedwith suitable openings to permit the push rods to pass therethrough, andat the same time cover the usual valve seats of the cylinder blockindicated at 19.

From the foregoing itwill be seen that I have provided an engine head,wherein the usual engine head may be removed and replaced by an enginehead constructed in accordance with the invention, converting the usualenclosed valve engineinto a valve in the head type. 7

Having thus described the invention, what is claimed as new is 1. Anengine head having intake and exhaust openings, pairs of exhaust valvesfor controlling the passage of exhaust gases other, means forcontrolling the movements of the valves, said means including an outerrocker formed with an opening and an inner rocker positioned Within theopening. and a push rod for operating the exhaust valves simultaneously.p

2. An engine head having intake and exhaust openings, exhaust valvesarranged in pairs for controlling the exhaust gases from the enginehead, a pair of rockers for controlling the exhaust valves, and a forredpush rod cooperating with the rockers for operatingthe exl'iaust valvessimultaneously.

3 An engine head having intake and exhaust'openings, exhaust valvesarranged in pairs for controlling' the passage of exhaust gases from theengine, intake valves for con trolling the passage of fuel to theengine, pairs of rockers, a bracket member for supporting each pair ofrockers and a push rod for operating the valve rockers simultaneously.

1-. An engine having intake and exhaust openings exhaust valves arrangedin pairs for controlling the passage of exhaust gases from the engine, abracket member an outer rocker member and an inner rocker membersupported by the bracket and cooperating with the exhaust valves foroperating the same simultaneously, and a push rod having means at itsupper end for contacting with the rockers tooperate the rockers and exhaust valves simultaneously.

In testimony that I claim the foregoing as my own, I have hereuntoaliixed my signature in the presence of two Witnesses.
